An Allocated Cost is a type of expense that is clearly associated with and so can be readily assigned to a certain business process, project or department. Allocated cost types might include fabrication costs, sales costs, project management costs, and associated fixed costs. Another example, a company might allocate or assign the cost of an expensive computer system to the three main areas of the company that uses the system. A company with only one electric meter might allocate the electricity bill to several departments in the company.

- Standards promulgated by the CAS Board, if applicable, otherwise, generally accepted accounting principles and practices appropriate to the circumstances
